How is prediction and prevention of cardiac arrest?

Primary prevention is identifying risks, secondary prevention are measures taken to prevent recurrent arrest after one has already occurred. Only practical strategy is risk control (age, smoking, cholesterol, DM, BP, LVH, CRP) After major CV event (MI) risk of death is highest in 6-18 months after the event, and platues baseline of underlying disease. Rate of resusication depends on mechanism of event, pulseless VT has best outcome, then comes VF. asystole and PEA have dismal outcome stats
